What are meshes?

- [Instructor] Before we start talkingabout meshes too much,I want to kind of show you what meshes are.Now, this is Fusion.Now, this is a model of a decanterthat we used in a previous lesson series,but this is not a mesh.This is a few different faces.You can kind of see, hovering over,we have a few different areas that we can click on,maybe inside of here.But this is a mathematical formulathat describes this decanter.Let's switch over to Meshmixer.

And this is the front door to my house.So in Meshmixer here,I used my camerato take probably 30 or 40 different picturesof my front door,and that turned it into a three-dimensional meshwith color information.So if I just take off the color information,this is the 3D model that was generatedessentially for free using 123D Catch,which is a photogrammetry software from Autodesk.

Now it's not terribly detailed,but the really cool thing about this isthat this all proportional.If I go and measure my door,I can say, similar to how it works in Fusion,that from here to here is six feet or seven feetor whatever it might be,and then the entire model is now scaled proportionally.I can use this in all sorts of places inside of Meshmixerbut also bring it back into Fusion.If I press W,we see that this is lots and lots of little triangles.

This is a mesh.The decanter can turn into this if you export it,but this is not some mathematical formulathat represents the door.This is exactly a combinationof about 200,000 triangles.I can go in with various toolsto change the number of triangles.So I can actually go like thisand use a tool with no strength at all.But just go in, and you can see that I amchanging the number of trianglesusing some remeshing right here.

I change this, and change it.Right, so this is very different than Fusion 360,but it gets very, very subtle little pieces of detailthat Fusion might not be able to get.That is the basis of what we're going to be talking aboutinside of this mesh section inside of the class.

Design differently with Fusion 360. This cloud-powered tool from Autodesk—the makers of AutoCAD, Inventor, and Maya—is the key to instant 3D creativity, used for computer-aided design, manufacturing, and engineering (CAD, CAM, and CAE). This essential training gives you the expertise to use Fusion 360 to turn your ideas into ready-to-manufacture designs. Nick Kloski provides an overview of all the basic operations in Fusion 360, including sketching, extruding 3D objects from sketches, 3D modeling, sculpting, and surface modeling. He explains the functions of the software, while providing a solid foundation in the basics of effective 3D design. Learn how to plan a project; model your ideas; work with sketches, meshes, and surfaces; generate files for 3D printing; and run simulations on your designs.

Note: This course was created and produced by HoneyPoint3D. We are honored to host this training in our library.
